This RC-scale front lower suspension arm is designed for the Tamiya DT-03 chassis and is identified as model JR-DT300-LB. The machined aluminum construction provides a true mounting face intended to help maintain accurate alignment of front suspension links and wheel hubs on 1/10 on-road models.
Installation uses the DT-03 lower arm mounting points and standard fasteners; verify correct orientation and ball-joint alignment before final tightening. Being a metal component, it changes front-end stiffness compared with some composite parts, so you may notice slight differences in steering response as part of tuning work.
Made for tuners who need fine control of front-end geometry, repeatable setups and a durable option for on-road use. Always confirm compatibility with your specific DT-03 variant and check the product listing for included items.
Fit this aluminum front lower arm to improve the repeatability and stability of DT-03 front suspension geometry, checking fitment before final installation.
